This is the User guide for the Atos Sequana XH2000 HPCF, installed in ECMWF's data centre in Bologna. This platform provides both the HPCF (AA, AB, AC, AD complexes) and ECGATE services (ECS), which in the past had been on separate platforms.
Below you will find some basic information on the different parts of the system. Pleaseclick on the headers or links to get all the details for the given topic.
From the automatic purge of unused files in SCRATCH is enforced. Any files that have not been accessed at any time in the previous 30 days will be automatically deleted. This purge will be conducted regularly, in order to keep the usage of this filesystem within optimal parameters.
